    CHANGES WITH THIS ADVISORY:

    None.

    SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

    A Hurricane Watch is in effect for...
    * Southwestern peninsula of Haiti from the border with the
    Dominican Republic to Port-Au-Prince

    A Tropical Storm Watch is in effect for...
    * Jamaica

    A Hurricane Watch means that hurricane conditions are possible
    within the watch area. A watch is typically issued 48 hours
    before the anticipated first occurrence of tropical-storm-force
    winds, conditions that make outside preparations difficult or
    dangerous.

    A Tropical Storm Watch means that tropical storm conditions are
    possible within the watch area, generally within 48 hours.

    Interests elsewhere in Haiti, the Dominican Republic, and Cuba
    should monitor the progress of Melissa.

    For storm information specific to your area, please monitor
    products issued by your national meteorological service.


    DISCUSSION AND OUTLOOK
    ----------------------
    At 800 PM EDT (0000 UTC), the center of Tropical Storm Melissa was
    located by an Air Force reconnaissance aircraft near latitude 14.3
    North, longitude 74.5 West. Melissa is drifting toward the west
    near 1 mph (2 km/h). A slow forward speed and a gradual turn to
    the northwest or north-northwest is forecast during the next couple
    of days, followed by a westward turn by this weekend. On the
    forecast track, Melissa is expected to be nearer to Jamaica and
    the southwestern portion of Haiti later this week.

    Maximum sustained winds are near 50 mph (85 km/h) with higher
    gusts. Some slow strengthening is forecast during the next few
    days, and Melissa could become a hurricane by Friday, with more
    substantial intensification forecast by this weekend.

    Tropical-storm-force winds extend outward up to 115 miles (185 km)
    from the center.

    The estimated minimum central pressure is 1002 mb (29.59 inches).


    HAZARDS AFFECTING LAND
    ----------------------
    Key messages for Melissa can be found in the Tropical Cyclone
    Discussion under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC.

    WIND: Hurricane conditions are possible within the watch area in
    Haiti beginning on Friday. Tropical storm conditions could begin in
    Jamaica late on Thursday or on Friday.

    RAINFALL: Melissa is expected to bring 5 to 10 inches of rain to the
    southern Dominican Republic, southern Haiti, and eastern Jamaica
    through Saturday, with locally higher amounts possible. Additional
    heavy rainfall is possible beyond Saturday. However, uncertainty
    in Melissa's track and forward speed reduces confidence in exact
    totals. Significant, life-threatening flash flooding and numerous
    landslides are possible.

    Across Puerto Rico, northern Dominican Republic, northern Haiti, and
    western Jamaica, 2 to 4 inches of rain is expected through Saturday.
    Flash and urban flooding will be possible through at least Saturday.

    Melissa, please see the National Weather Service Storm Total
    Rainfall Graphic, available at
    hurricanes.gov/graphics_at3.shtml?rainqpf

    SURF: Swells generated by Melissa are expected to spread to
    Hispaniola, Jamaica, and eastern Cuba during the next couple of
    days. Please consult products from your local weather office.
